"Is it possible to get up to the bolts to set up an toprope on this route?" Usually at Rumbling Bald, the answer is no. The cliffs are set into the mountain side, and are usually protected by jumbled masses of steep rock and/or gullies. This wall has a gnarly gully that could be ascended, and maybe you could reach the Mojito anchor, but it would be just as dangerous as leading the route itself! Or close to it.
